Add operator list (in case MNO cannot be determined automatically)

[Torsten Lodderstedt]

in case the MNO cannot be determined based on the parameters supplied by the RP, the discovery service shall provide the RP with a list of potential operators. This is especially useful for native apps. They can provide the user with a list to select the MNO from.

Questions: - Is it possible to filter the list down? Could be possible since SP has to sign up for MNOs - How would this list be sorted? - Is it really useful to have a list? Alternatively, the client could also use the user interaction endpoint in case of an error.
